The article discusses how studying enzymes can help students understand how biology and chemistry are related. Several inquiry-based lab activities demonstrating how hydrolase and oxidoreductase enzymes function in food are described. A demonstration using marbles and bits of pineapple in gelatin will demonstrate how the enzyme bromelain reacts with gelatin. Suggestions are provided on helping students design experiments to measure how temperature, pH, and concentration affect fruit enzymes.
